RD600 first look and general questions

[Mekrel]

Hmm not getting this at all, can't seem to get stable at 3.6 at all.

Processor is L628B Which I thought was a good stepping, so I think it maybe the board.

Having to run in yellow dimms being as ornage refuse to run dual channel and the board also makes a whine noise when under load. Done all this from the very start. Maybe time to RMA.

Edit: I can get 3.2 with no voltage increase, after that then it seems voltage has to be used.

not all e6600 of any stepping will hit 3600..and I find going from 3420(1.4625) to 3507 needs 1.52v..about .06...big jump

you will need to boost vcore and as you increase the chip may need a fair bit more vcore to hit that speed

also as you increase fsb the NB will need more volts

I would suggest setting vcore to at least 1.5v and see what you get ..but increase NB to at 1.42v to help reduce the chance the chipset is a factor

the bolded values will help alot in most cases...give extra voltages at first and then you can tweak them

The new bios isn't important uh? There 're only little changes.

Is it possible that the heat from the NB Heatsink could damage the PCIe slot?
The screen shows all blues as greens now when I browse the net or click on a icon since my first benching session. I know it sounds crazy, but it worked fine up until that point. I have tried the card in other computers and it works fine not showing this issue....

Bios showed 75~85 degrees celsius(Depending on how accurate it is) while I was benching. It was a 3 hour period of this. I had two 120mm fans running on it and it felt cool to the touch. I assumed it was a reaction to the board under stress and that it would go back to normal under stock conditions, but the next day it was still showing this issue. Any thoughts?

[ooeric]

three words? r m a

[raidflex]

I still cant figure out why the board will not go past 450FSB. Played with just about all the settings I can. The CPU goes to 7x450 with Vcore on AUTO which is pretty darn good anyways. But I figured maybe it just needed more voltage for higher mghz/FSB but I can give the CPU 1.55V and still will not POST correctly after 450FSB. Is it possible this is just the limit of the CPU and it will not go any higher, or is it just the board refusing to go higher? I also tried raising the NBcore up to 1.8 or 1.9V but not for long as this is way too high I just did it to see if it would pass 450FSB and it still refuses to. I am curious to see if this CPU will go higher, i mean it it does 3.15gig at stock voltage so why wouldn't it be able to do another 100mghz?

[Brian y.]

It should not be the board limiting the FSB. You have to give more voltage to the NB.

I was having the same issues. Once I raised the the NB voltage I was able to max the board out. The highest I could get the board was 530FSB. Just make sure you have proper cooling on the chip set.

[Praz]

Just make sure you have proper cooling on the chip set.

Above 1.53V on the nb aftermarket cooling is a necessity. And the chip isn't going to last with high voltage 24/7.

[raidflex]

yeah i added a fan to the NB heatsink max load temps are about 55C. and idle is about 50C. That is NB Core on 1.52V I tried maxing out the NB voltage but it didn't seem to help. i also messed around with all the voltages concerning the NB but ti still refuses to POST correctly past 450FSB. I dont want to go above 1.5V for long periods because from what i have read it could damage the the Motherboard or CPU.

Oh yeah I tried the 2/12 BIOS and it wont boot from a USB keyboard with the new BIOS it just goes to a black screen after the logo displays and stays there. I plug in a PS2 keyboard and it works fine.

anybody know how changing the GTL ref voltage on cpu affect cpu life

I saw a post that seem values of 70-80 are helpful per Tony aka Big Toe(supposedly better than 48/48)
I changed mine to 70/70/128 and was able to lower cpu vtt from 1.23 to 1.21...according to Intel papers cpu vtt of 1.26 is max and on my mobo 1.23 bios=bios reading of 1.26

also Iwas able to load winxp at 3600 at same vcore as 3500 and this usually would just hang on screen after the initial post

look at last post

what I am not sure is if you should increase the NB GTL?

not sure how this affects the cpu/mobo life

To start with you have to Enable GTLRef to have the setting take some effect, Oskar has preprogrammed good auto settings but they can be improved on as each processor does respond in different ways to voltage tweaks.

In my original guide Oskar had informed me to tweak up from 0 to 48 for the CPU GTL voltages, we have now found this is not the best option. Thru the work of many end users using dual and quad core CPU's we have found increasing over 48 is best to increase the FSB the cpu will run on. Also please rememer DFI have locked core 0+1 and 2+3 together for adjustment, they did this as this is how they are latched onto the FSB. Here are some points to remember.

1 If using a quad core you should only need to increase GTL for core 2+3, signalling to 0+1 is usually OK at auto unless you are seeing a huge FSB hole.

2 Increase GTL values BEFORE CPU VTT, this is VERY important, only increase VTT if GTL has zero effect or makes things worse.

3 Increase GTL voltages in preference to NB Vcore voltage. While an increase in NB core voltage does have a huge effect on FSB overclocking you do need to keep the NB core voltage as low as you can to ensure the NB has a long life.

Now the final question....What is the optimal settings for the highest FSB?

The answer is every CPU is different, some have found setting between 70 and 80 best on the CPU, some have even run 120+ so it all depends on what the CPU cores need to open up the FSB. be prepared for a lot of tweaking and testing...but as Kris has shown it is possible to gain quite a few MHz if you are willing to put in some time testing.

I have increased the GTL 80 80 70 and it's runs fine (Orthos 7h stable 1h less to finish). Vcore is 1,42.

so you lowered the NB to 70???

did you lower other mobo voltages?

[Raja@ASUS]

the gtl values were taken from intel specs using the voltage scale used by oskar in the bios, shrek posted a link to this at dfi club, having used the nearest to spec on dual core and found it worked better. Quad core needs higher gtl ref voltages. In terms of component life using GTL I would not concern myself excesivley, you are far more likely to hurt compnents with vnb and vcore and vdimm than gtl ref . Remember to stick within 75-85 on most dual core cpu's and you should be ok for higher clocks booting up stable.


Pcie is a voltage we routinely abuse on most boards, on this board near staock works best once gtl is tuned..

Great info

I am finding at 1.36v on NB...if I want 450 ram speed I need to increase from default my NB PLL 1.2v to 1.29 and PCI-e 1.2v voltage to 1.34

Still not sure I am stable but closer

HMM..I may try 85....

so you lowered the NB to 70???

did you lower other mobo voltages?

No, other mobo voltages are setting up.

I got another problems. Maybe anyone here could help me to solve it.

It's the speed problem with my HDD and I haven'T found a solution.

OK..I reread Kris artice at tech repsoitory...it seems the disabled default values are more in line with intel spec of 2/3 vtt for cpu ref voltage than when you first enable it in bios(48/48/128)

GTL ref voltage should be closer to 75-80 for the cpu..I have no idea on the NB

I disabled GTL ref voltage as it supposedly is more in line with Intel spec..48/48 is on low side.... 75 or so in spec

[AbelJemka]

If the goal if to keep all in line with Intel specs what it's the point of overclocking? If u think Intel specs must be folow stickly please minus ur vore from 1.51875 to 1.35 if u don't ur cpu to be blows in the second

Did you look at any of the links I posted above....Jeez...I am not advocating using less....or following just intel specs..crap you always are looking to crap on posts

Sorry..you missed my point 48/48..applies less GTL ref voltage..which is what many are using

70-80 values actual are closer to Intel spec...therefore if you want more voltage you need to be higher than 48..which Tony aka Big Toe and freecableguy note in the links above

here just look at this link and you will hopefull see my point

I am serious looking at WCing block but I really hate the idea of rd600 specific block and while I like a MCW30..I am not sure the clip menchanism will keep a good tight fit with my tube routing

I got a redundant DD RD600 block if you want it m8y!?
It's as much use as a chocolate Fire-Guard for me now!
PM me if you want it...Pay Pal is cool this end.
Swap it for a DD 680i if you can get one.....None in the UK atm.

I have rd600 with gskill memory 2*1=2gb. But it doesn't works with it.I try to use new bios in dfi's web site but it doesn't works too. Before ı buy to rd600 ı dıdn't know gskill memory didn't works with rd600. So what can ı do ? to use gskill memory with rd600.Anyone else has Gskill memory and use rd600 without problem ??
